ET's Denny Directo was on hand for the death-defying acts and amazing vocal performances for the first night of America's Got Talent's live performances, but what got us most was Simon Cowell backstage talking about his next big act -- his son Eric.

"He's doing amazing!" Cowell told ET. "He's like two and a half years old. He loves music, loves dancing. He's going to follow me into what I do. I know that."

Cowell previously opened up to ET about Eric back in May, where he said, "He does remind me of when I was younger because he knows how to get away with things." During the same interviews he also admitted that initially he wasn't sure if his son liked him.

"They don't respond to you and they cry and I thought, 'Oh God, maybe he'll never like me,'" Cowell said at the time. "Then one day he started talking to me and it was, 'Oh my God!'"
